Abstract:
To study the regularity criteria of solutions, the three-dimensional axially symmetric incompressible magnetohydrodynamics (MHD ) equations with swirl are presented. Two types of particular weak solutions to the three-dimensional axially symmetric incompressible MHD equations
uθ =0,
Br=
Bz=0, and
Br=
Bz=0 are considered. By using the energy method and the embedding method, the regularity criteria for the two types of weak solutions to the three-dimensional axially symmetric incompressible MHD equations are obtained if the radial direction component
ur satisfies some conditions.
